pH Measuring

ColorpHast pH Test Strips

ColorpHast pH test strips are made with a non-bleeding cellulose indicator tip bonded to a plastic strip. Because they are non-bleeding, they will not contaminate sample solutions. One to four, colored cellulose pH indicator squares are bonded to each strip permitting testing of a full pH range with a single strip. To find the pH of a sample solution, wet a pH indicator strip in your sample solution for a minute or two and compare the color of the strip to that of the reference chart located on the container of the package. Each pH range of strips come packed 100 strips per container.
